Learn how Vite’s native ES module serving eliminates bundling in development, giving near‑instant start and precise Hot Module Replacement, with a concrete setup example and notes on browser support and monorepo considerations.
Vite serves source as native ES modules, eliminating dev-time bundling. HMR updates only the changed module chain, preserving state. Trade-off: first-run dependency pre-bundling can be slow for large projects.
Learn how to configure Vite's HMR for Docker and WSL2 to prevent full page reloads and maintain application state during development.
Vite's speed comes from two decisions: serving source as native ES modules and pre-bundling dependencies once. Here's how both work, how to verify them, and where they break down.
An architecture note on Vite's HMR: why serving native ES modules instead of a bundle makes updates near-instant, where the trust boundaries sit, and the circular-import and dev/prod divergence failure modes to watch for.
The integration boundary in a SolidJS project is formed by the SolidJS compiler (provided by vite‑plugin‑solid) and the Vite dev server. When the plugin, Vite, or Solid major versions drift beyond the peer‑dependency ranges declared in the plugin’s package.json, the JSX transform may break, reactivity ownership can become duplicated, and hot‑module‑replaceme
Vite uses a dependency graph to manage Hot Module Replacement (HMR), allowing modules to opt-in to updates via import.meta.hot . When a module is updated, Vite attempts to invalidate only the affected branch of the graph to avoid a full page reload. A challenge arises when circular dependencies exist within the module graph. In these scenarios, the HMR bound
